[Macos-users] Mavericks and ROOT
by Jeroen Van Tilburg 06 Nov '13

Hi, For those of you that have not yet upgraded to Mavericks and occasionally develop code or run ROOT locally, you might consider waiting a bit before upgrading. For those that could not wait to get the new OS (like myself), below are some instructions to re-install ROOT. In case you find mistakes or misconceptions please correct them. o First, why to reinstall ROOT in Mavericks. When compiling something in ROOT you will probably encounter: "Undefined symbols for architecture x86_64" When this happens, this means you need to reinstall ROOT. o Prepare for re-installing ROOT from source after Mavericks update. You need to (re-)install the command-line tools for Xcode: xcode-select --install Then remove XQuartz and reinstall the latest version (download from web or App Store). You need to do this even if you already had the latest version *before* upgrading to OS X Mavericks. Visit: http://xquartz.macosforge.org/landing/ o Install ROOT from source. It seems that you need to get the latest ROOT patches, otherwise PyROOT will crash. git clone -b v5-34-00-patches http://root.cern.ch/git/root.git root-v5-34-00-patches cd root-v5-34-00-patches ./configure macosx64 --enable-roofit make -j6 source bin/thisroot.sh o In case you use PyROOT, you will notice that the X windows are not appearing. This is because PyROOT thinks it is running in batch. The workaround is to add at the start of your script, or in a .pythonrc file: import ROOT ROOT.gROOT.SetBatch(False) After that you can do things like from ROOT import * TBrowser() in your scripts. See https://sft.its.cern.ch/jira/browse/ROOT-5673 and http://root.cern.ch/phpBB3/viewtopic.php?f=14&t=17238 It took me 1.5 days to get this working. I hope this saves some of your time. Cheers Jeroen

(brief translation: the familiar Xerox printer driver problem of submitting spurious jobs gets even worse under Mavericks, because you don't even see those jobs anymore) Question: A perfect work-around under Mountain Lion is to ignore "Follow-you" printing and submit directly to (for example) H3. No spurious jobs, printout comes out directly. Is this still true with Mavericks? And has anyone encountered anything else with Mavericks at Nikhef that might be a reason not to upgrade?
